To aile/#10m may concern Be it known that l, loswnLL A. Lancer, acitizen oi the TUnited States, residing at Townsend, in the county oic Middlesex and State of lvlassachuseltts, have invented certain neuv and useful lrnprovements in LeatherBoard Machines; and l do hereby declare the "following to he a full, clean and exact description of the invention. such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to an improvement in leather-hoard machines and more especially to the mechanism for auto` inatically severing and removing the sheetr of stoel; 'from the collecting roll after a predetermined thiclness of stock has been Collected upon the roll. ln the machine of my Patent lilo. 1,016,945, the stock severing knife was supported inside of the collecting roll and projected outward through a slot in it when the material Was to 'ne cut. The space within the collecting roll which received the knife and its supporting-and operating parts was cramped and involved the use of a construction which Was more or less liable to derangernent in use.

@ne object of the present invention is to `produce a cutting-ofil mechanism operating from outside the collecting roll. ln the construction of my patent, :means was employed to direct a blast oi' air between the stri per plate and the stock so as to assist 'in tide separation oi the stock from the collecting roll. This use of compressed air in stripping the stock from the collecting roll is of great importance in facilitating the operation of the machine and thepresent invention contemplates providing improved means for applying and using a hjlastfof air in assisting the stripping of the stock from the collecting roll.

Other objects of the invention Will he ohrious to those skilled in the art from the following description of the invention.

To the above ends. the present inventionconsists in the leatherhoard machine hereinafter described and particularly defined in 'the claims.

The illustratedA embodiment of the inver tion is descrihed as follows: The collecting roll l0 is a cylindrical roll gudgeons ll supported in bearings l2 earried by the frame orf the machine. On the end o1 the gudgeon il isvmounted the gear used in connection. with the which meshes, with" the gear e mounted place the valve for operating 65 carried by 7G on the knife shaft 15.' The knife shaft 75 supported in proper position Withrelation to the collecting roll hy the 'links 15 and l?. The link 16 einhracesthe linie shaft 15 at one end and the gudgeon ll of the collecting rol-l l0 at the other and serves to hold the SG knife shaft and collecting roll at a constant distance from each other. This is a feature of some importance as in the operation of the machine when the knife strikes the collecting roll, the cutting action of the knife. tends to separate the axes of the knife shaft and collecting roll, The links 16, of which there 4.are two.y one at each end oie the collecting the resistance of the stock to 85 roll, vtake up this sarees eiiiciently, because 9o they are located close to the place Where the strain is exerted onthe parts. rEhe link 17 embraces at its upper end the knife shaft 15 and supports it in a vertical position. The

journal hearings 12 present large areas and 95 aiiord a good support for the collecting roll in the frame of the machine. Mounted upon the bracket 20 above the journals l2 is the bearing 2l for the stripper shaft 22. To the stripper shaft is secured the stripper carry- 10o ing arm 23, the outer end of which rests which supports the the collecting roll z5 from pip/e 30. The air v'al moves to the position shown in lig. o,

stripper in the position illustrated in Fig. 1 with the stripper plate lifted above and out of' :onta ct with the collecting roll. The compressed air supply from .the valve 25 leads 5 compressed air through the pipe '26 to the stripper.

rThe collectingr roll ,qudgeon 1l is hollow and provided at the center with an' air pipe 3U. which extends Jfrom the inside of through the length ot' the. ,frudgeon and out beyond its end, as shown in Fig. The outer end of the air pipe 3() is closed. On the outwardly projecting end of the air pipe 30 there is mounted an air distributer casing' 31 which is connected by the pipe 32 with the air 'Valve Q5.

air is allowed to tlow as above described through the pipe 2G to the stripper and through the pipe 32 to the air distributer be injected through the holes ffii, a row of 'which extend along the collecting" roll near the position of the cut. This air, passing out through the 4holes B-Ltends to loosen theforward edge of the severed board.

This is a feature of importance in thisymachine. lt causes the bo`ard to be loosened, or tends to cause it to be loosened, and to lift up thev advancing edge of the severed board so'Y that when it strikes the stripper 40 Si), the stripper engages the lifted edge of the advancing,r board and drops under it and throws the board ol'l the collecting roll.

The pipe 36 extends; along the back of the and has ducts 40 which discharge the air into the leads 4l which conductg the stripper air to the `frooves il? in the lower edge of the stripperf lVhen the board engages the stripper the air pressure under `the board tends to lift-it and the air pressiile exerted on the board between the stripper and the board causes the board to slide smoothly along the stripper, so the advancing edge ot the board is lifted' by the blast of air lischarged through the ports in the collecting roll and then the lifted edge, is caught by the stripper and the movement of the board on the stripper is facilitated by the blast ot air which is discharged between f-thef-stripper and 'the board. so that the board is turned forward and thrown over the knife shaft Yl5'.

The knife shaft 15 is intermittently connected with the gear 14 by which it is driven by .means of a clutch de\'ice""which G5 causes the Vknit'e shaft to be engaged Then the air valve 25 is/@perf operating slide GO.

Ymounted in a slideway 61 secured to the by the gear and to be driven by it for one resolution and then disengaged from it. The connections between the gear 14 and its shaft l5 permit .a vnice adjustment of the timing of the out Imade b v the knife. Connections are also provided for operating the striliiper in timed cooperationv therewith andthe aiij"biast"t'iir the collectingrroll and the stripper. .On the end ot' Ythe knife shaft lsplined'the clutch sleeve 50, the clutch f member .51 of which is adapted to engage the clutch member of the gear 1%. lVhen the clutch member 51 is movedato the lett, as viewed .in Fig. 2, the face, 53

engages the corresilionding face 54 of the. clutch member 52, and so the knifeshaft is driven by the rear and provision is made for disconnecting: these clutch members at the end of onel revolution of the knife shaft. The clutch member 5l is provided with a groove 55 which is engaged by apin 56 which is rigidly connected with the clutch This clutch sliderGO is frame niet the machine. The right-hand end of the slide GO is engaged by the bell crank lever G pivoted at (il upon the frame of the machine and normally pulled upon by the springL G5 to turn it in a direction to move the clutch slide G0 in the direction to cause the engagement of the knifeI shalt clutch men'ibers. latch 70 slidingr in. a
